Dement And Kleitman Essay
Maisarah Mahusin Block 5 5/4/2015
Dement & Kleitman experiment is to find out the relation of eye movements during sleep to dream activity. There are three hypotheses that they wanted to test in this study, first there will be a significant association between REM and dreaming, second there will be a significant positive correlation between the estimate of time spent dreaming and the length of eye movement and lastly there will be a relationship between pattern of eye movement and the reported content of the dream. I considered Dement & Kleitman experiment to be valid.
One of the factors that has made the findings to be valid is the use of laboratory experiment. This enables the use of advanced technology and allows for precise measurement of data which in this case, EEG machine (electroencephalogram) is used to measure the brainwave activity and measure the eye movement of the participants which are not directly observable to the naked eye. By using this experimental method, it can strictly control the situations or conditions, ensuring IV (independent variable) affecting the DV (dependent variable) nothing else made the findings to be valid. For example the participant variable was controlled by prohibiting from consuming caffeine and alcohol on the day of the experiment and controlled the situational variables by standardizing the procedure e.g. they were give same instruction and same equipment is used. In further, with the tightly controlled situations, they were able to draw conclusion about the cause and effect relationship e.g. patterns of eye movement is associated with dream content.
Another factor that has made the findings to be valid is the use of sophisticated machine, EEG machine. These are the results of the three hypotheses I have mentioned in the introductory paragraph. The result for hypothesis 1 was that participants were much more likely to recall
